Allen Bradley 8400 info

Hello, I bought a Lagun mill with an Allen Bradley control. It all works well but I have no manuals with it. I have Fanuc programming experience but can't figure out how to set a coordinate system up on this thing. It uses "Fixture offsets" which I think is the work offset, I tried adding the G45 and offset number in my program but no luck. Does anyone have any experience with this control or have a working program they could send me, or any ideas? I would gladly buy a programming manula if I could find one too.

Re: Allen Bradley 8400 info

you may be able to buy a programming manual from Control Sales and Service in Lewisville Texas or Albright's CNC Support Services in Bozeman Montana. I've gotten Allen Bradley CNC stuff from both of them.

Longer than I have the ability to remember I used to help build custom machine tools that used 8200 and 8400 Allen Bradley controls. Let look through my pile and see what I can find. I do know I have a bubble memory (for the control lol) if you need one of those. I'll see what I can find and shoot a post off asap ...

Re: Allen Bradley 8400 info

I got the Fixtures part figured out finally, it has 12 fixture offset settings on one page. It has a "Last offset" setting for some reason, and that setting was set to zero, so it wouldn't use ANY of the fixture settings. Why you would want to block some offsets I don't know. I still can't get it to use G42 or pick up a tool offset so some info there might help now, maybe just a sample file with the initial settings on it.
